Abstract
An electrical switch assembly includes a printed circuit board having a planar switch pad thereon. An actuator is mounted for pivotal movement relative to the printed circuit board about a pivot axis spaced to one side of the planar switch pad. A planar switch contact on the actuator overlies the planar switch pad on the circuit board. The planar switch contact is disposed at a predetermined angle to the planar switch pad when out of engagement therewith in an inactive condition of the actuator, so that the entire surface of the switch contact engages the entire surface of the switch pad immediately upon initial engagement.
Claims3
An electrical switch assembly, comprising:
- a printed circuit board having a pair of spaced planar switch pads thereon;
- a rocker actuator fabricated of elastomeric material including an integral peripheral flange joined together by a peripheral flexible skirt, a fulcrum, and wing portions disposed on opposite sides of the fulcrum;
- the actuator mounted above the printed circuit board by the peripheral flange held to the printed circuit board with the fulcrum in contact with the printed circuit board where the flange and fulcrum are adapted to allow the actuator limited rockable movement about the fulcrum between the spaced switch pads;
- a planar switch contact on each wing portion of the actuator overlying the planar switch pads on the printed circuit board, the planar switch contacts being disposed at predetermined angles to the planar switch pads when out of engagement therewith in an inactive condition of the actuator such that the planar switch contacts move about the fulcrum into engagement with the planar switch pads to effect initial and immediate mutually planar abutment therewith
- one of said wing portions of the rocker actuator, alone with its respective planar switch contact, adapted to move toward the respective planar switch pad independent of the other wing portion of the actuator.
